Steps to reproduce

When an error is reported when I query the system.settings_changes table, the current connection becomes invalid. Or it can no longer proceed with other query requests.

because this issue: #456

public static void main(String[] args) throws Exception {
        Class.forName("com.github.housepower.jdbc.ClickHouseDriver");
        Properties clickHouseProperties = new Properties();
        clickHouseProperties.put("user", "nethouse");
        clickHouseProperties.put("password", "xxxxxxx");
        Connection conn = DriverManager.getConnection("jdbc:clickhouse://10.185.206.152:9120/NETHOUSE",
            clickHouseProperties);
        try {
            ResultSet resultSet = conn.createStatement().executeQuery("select * from system.settings_changes");
        } catch (Throwable e) {
            // e.printStackTrace();
        }

        System.out.println("isClosed: " + conn.isClosed());
        System.out.println("isValid: " + conn.isValid(2));
        try {
            ResultSet resultSet = conn.createStatement().executeQuery("select * from system.clusters");
        } catch (SQLException e) {
            // e.printStackTrace();
        }
    }

@dmitrybugakov Hello, my friend, is this open source software unmaintained now? I found a lot of problems that didn't close and didn't adapt to the latest ClickHouse version.

Hello @beijishiqidu

Unfortunately, I don't have time right now to actively maintain this project. Regarding your notice, it could be because we are testing against a "clickhouse-server:21.9" version.
